Essays on Stem

The contemporary world has seen the exponential rise of cancer prevalence in the aging population to somewhat alarming levels. This segment consists of individuals aged 65 years and above and is the fastest growing age group in the United States. Recent statistics indicate that one in every eight people in America aged 65 years, and above develops cancer, with women accounting for 58% of all cancer cases (Browner, n.d.). Since cancer risk increases with advancing age, the elderly account for 56% and 70% of all new cancer diagnoses and mortalities in the country (Browner, n.d.). The cancer burden in ...

Higher education in the United States faces a number of challenges because of the opportunity gaps that exist in the society. The opportunity gaps stem from the increase in immigration of minority groups in the society and the lack of affordability for higher education in these minority groups. Despite the current arguments in the United States that there is the attainable American Dream, there are still those persons who cannot access or afford higher education. The truth is that children of lower socio-economic groups will have a more difficult time accessing higher education and this leads to the limitations ...

Introduction

Over the past, the military and natural sciences have been overly male dominated fields. However, tireless and lengthy legal and professional advancements have borne fruits because women are single top growing subgroup in the military profession. For instance, Pentagon expressed its commitment to lift the ban, which would see more women in the combat role; nonetheless, underrepresentation of women in the forces is still significant as indicated by Eager (2014). Therefore, the essay will investigate on capability and role of women on the battlefield frontline considering that technology and other factors have changed the role of officers in wars. ...

Introduction

Fostering diversity and multicultural inclusion in STEM majors is one of the most problematic areas on the today’s business and academic agendas (Barzilai, 2005). Duerstock and Shingledecker (2014) argue that the practice shows that attracting culturally diverse interns to the professional and educational fields is an effective approach to cultivating equitable working environments. Although a number of informative studies have been conducted to analyze theoretical perspectives of the problem, brining cultural diversity to the workplaces is still practically and conceptually impoverished, especially in the public segment of economy (Ross, 1985). The scholars and the practitioners unanimously agree on ...

Embryonic stem cells are produced from embryos, human or other animal embryos

.most of such cells have developed from embryos that develop from eggs which have been fertilized in vitro fertilization clinics. Such embryos have been donated for the purpose of research with the informed consent of the donors, and they are certainly not developed from eggs fertilised in a woman’s body. (Bethesda, 2015)

At the outset it has to be accepted that the embryonic stem cell research is a modern

day scientific marvel which can change the ways the various presently day incurable human ailments, are treated in the future. Diseases like cancer, Parkinson’s, Alzheimer’s, premature aging, stunted growth may altogether be eliminated in the distant future.

Introduction

This project will compare the cost of gym memberships at two well-known fitness centers in Northern Colorado. Information will also be gathered on known alternatives to gym memberships, such as the purchase of pay per class mobile apps and home gym equipment. It is assumed that corporate gym discount membership rates at both Northern Colorado facilities are unavailable. While approximately forty-four percent of employees desire some type of financial support from their employers when it comes to making healthy lifestyle modifications (Beagrie, 2015), for simplification purposes the project will assume the individual does not work for a traditional employer. ...

Microbial Genetics

This is an area of study within microbiology and genetic engineering that studies the inheritable characteristics of microorganisms. It is an area of study of great significance in the field of health and medicine. In this essay I will be focusing on this significance both positive and negative as it relates to the field of health and medicine and the new ways in which genetic engineering is finding its application. HIV infection usually infects cells with CD4+ markers. The other markers that are essential in making infection of these cells possible are CCR5 and CXCR4 without which cell entry ...

Abstract

The current antiretroviral drugs have been efficient in the management of HIV by suppressing the virus's replication. It has, therefore, helped in changing this virus from a deathly disease to a chronic infection. The utilization of extremely active antiretroviral therapy (HAART) calls for a lifetime prescription to prevent viral rebound by reducing the viral load to undetectable low levels. This high maintenance of treatment and the various side effects of the drugs and non-HIV related morbidity have led to the need for a better form of therapy. There has been an extensive study on stem cell manipulation done to develop gene therapy ...

More often than not, globalization is associated increase in development due to the interdependence between economies. Increased flow of information and technology as a result of globalization has led to the emergence of new economies. From one place to another, globalization has also been associated with the degradation of the moral fabric in some societies. This is especially when more liberal lifestyles from developed nations impact on the conservative lifestyles that people in less developed nations lead. It is surprising that as much attention has not been given to globalization and disease.

Owing to globalization, diseases travel faster than ...

Diabetes is a burning issue all over the world. World health organization has shown concerns on the prevalence and incidents of diabetes. In USA, 29.1 million people or 9.3% of the population; diagnosed or undiagnosed have diabetes. (CDC, 2012). As per National Diabetes Fact Sheet, 2011 215, 000 people in USA have type-I or type-II diabetes. Thus, diabetes is a disease penetrating all age groups.

More and more people are diagnosed with cancer, a disease that the medical profession has yet to find a cure. The pharmaceutical industry is rapidly growing, so there’s hope to eventually discover a medical cure for cancer. The industry is influenced by stringent government regulations, legislative oversight, consumer organizations, patients’ associations, medical scientific ...

According to Sigmund Freud, dream is the way in which a person’s spirit gets liberated from the external pressure and it is also a way by which the soul gets detached from the attachment to material. He also stated that dreams are camouflaged fulfillments of our subdued wishes. Dreams are nothing but images, thoughts, voices and other sounds, and many more subjective sensations one experiences when asleep (Bryant). One often dreams about known people, strangers, places one had been to, places one had never been to or never even heard of. Many a time, a dream is as common as recollecting some ...

In “The Brothers Karamazov” by Fyodor Dostoevsky made a famous claim that establishes the link between the existence of God and morality. Apart from the controversy related to the scope of the quotation, the discussion on the proper translation and interpretation of the words of Ivan Karamazov. For instance, in his article “Dostoevsky did not say it” D.Cortesi claims that Dostoevsky did not make such claim (Cortesi 1). However, the research by Russian-speaking authors shows that the original text of “The Brothers Karamazov” contains the statement under study (Volkov 1). Coming to the scope of the claim, one should concentrate ...

Selection from an 8 year-period of pulmonary valve replacement and cross sectional follow up of a commercially available biological valve, assessed with established and a new method

What This Thesis Is About

Pulmonary valve replacement is a procedure necessary in many congenital heart defects and in-valve degeneration cases. Surgical results are excellent, but the longevity of artificial valves is very limited. Our goal was to give a retrospective overview of methods and results from the year 2000 until 2008 at Rikshospital, as well as the prospective five year follow-up of a biological valve made from bovine pericardium. Follow up included clinical examination with ECG, echocardiography, spirometry, treadmill testing, echocardiography ...

- Summary After a heart attack, the restoration of the cardiac function depends on the ability of the heart to generate cardiomyocytes, or new muscle cells. The ability is, however, weak and wanes with age. The alternative strategy involves delivering the newly grown cardiomyocytes to the damaged heart tissue. It requires the use of either induced pluripotent stem (iPS) or the embryonic stem (ES) cells. Embryos are the only sources of ES cells. On the other hand, the in vitro reprogramming of adult differentiated cells transforms them into undifferentiated stem cells. The method allows the production of iPS cells ...

‘The Debate Over Stem-Cell Face-Lift’ is an article published in New Yolk Times and is written by Sally Wadyka. The article dwells more on the new face lift technology which involves injection of fats and stem cell on the wrinkled parts of the face (Wadyka 2013). This restores the youthful facial appearance of an aged person. The controversy arises from the debate on the issue where several researchers and scientist discredit the authenticity of this technology. This technology is based on biological composition of human skin and existence of non-differentiated body cells referred to as stem cells which are ...

Introduction

Robots are used predominantly in industry. More and more companies are making their production lines automated by the usage of programmed robots. This trend of using robots started way back in 1960s and 1970s and gained popularity in the subsequent decades. Education was one area which was not touched by robotic technology until 10-15 years back. The strong belief was that a robot could not enhance the learning process. In fact introducing a robot in the learning process might make it more mechanical than creative. However, perceptions have changed in the last few years and education field is seeing more and more ...

Cloning is done by removing the nucleus of an egg and substituted it with the nucleus from an embryonic stem cell animal .A tadpole was produced from an adult cell of a frog by Dr. Gurdon in 1962, but it was welcomed with great distrust since the adult cells cannot assume new ones. He removed the cell nucleus from a developed intestinal cell and injected it into a frog egg. This was to test if the genome could change. The egg was reprogrammed introducing nucleus and the genes were switched to a developing egg rather than duties of an intestinal cell. From the ...

Zaraska, Marta. "Is Lab-Grown Meat Good for Us?" The Atlantic. Atlantic Media Company, 19 Aug. 2013. Web. 7 Nov. 2014.

This article reports on the possible advantages lab-grown meat has over conventional meat. The first discussed advantage is the ability to alter the fat and iron content of the cultured meat. Saturated fats and heme iron are implicated in cardiovascular diseases, diabetes and also certain cancers. Nutrition can also be altered by fortifying the cultured meat with vitamins and minerals, much like in the addition of vitamins in fruit juices. Another advantage is the decrease in risk of zoonosis, which occurs when infectious diseases are transferred from farmed animals to people. There are also distinct environmental advantages of growing ...

Deoxyribonucleic acid, DNA, is involved in the manufacturing process of all proteins in the body. It synthesizes proteins that repair and replace worn out tissues in the body. Stem cells (undifferentiated cells with the ability to differentiate) researches have shown that cells from some regions of the body can differentiate into different tissues. Therefore, they can replace worn out tissues and hence function as a repair mechanism. These cells can be induced to become tissue or organ cells. Scientists argue that perhaps the stem cells may carry out similar functions as DNA hence can replace it. This paper seeks to ...

Introduction

Elodea canadensis is a perennial hydrophyte, which is native to the majority of North America and was first recorded in about 1836 from the British Isles (Hackney, 1992). Young plants at first begin with a seedling stem and roots grow in mud at the underneath of water. More adventitious roots arise at intervals along the stem. The leaves are translucent, bright green, oblong, 1-4 mm broad and 6-17 mm long, borne in whorls of three round the stem (Rose, 2006). It lives completely submerged.

Keywords : Gene therapy, Sickle Cell Anemia, Stem cells, lentivirus, β-globin

Project type: GBE-492 Genetic Engineering Project I. INTRODUCTION, BACKGROUND and AIM Sickle cell anemia is a devastating genetic disease which causes premature death. Sickle cell disease (SCD) is caused due to single amino acid change (glutamine to valine at position 6) in β chain of hemoglobin molecule, which causes the hemoglobin molecules to aggregate. These aggregated hemoglobin molecules make the red blood cells (RBCs) stiff and deformed (sickle shaped). These deformed cells block the normal blood flow. Although this disease is well-characterized, but no long-term treatment 1 is still available for this disease. The discovery of the sickle ...

1. New born screening tests are to detect a newborn baby for different diseases and disorders that might be knowable at the time of the birth. I agree with this practice. The argument against it is that it might taint the babies life since from day 1 the parents will be aware of serious complications. I think this can easily be compared to buying a car. You would want to know what issues you face in the purchase of it.

2. Cloning in biology is when two different animals share the same DNA. So far there has not been huge ...

1. Personal Development, Life & Work Experience, Activities and Adversities:

As a child, I found it humbling how ants – those tiny creatures belonging to an ancient species – achieve huge goals by functioning as a harmonious collective. Humanity’s success as the master race on this planet also relies on our interdependence as a harmonious community, but crucially, the willingness to innovate and disseminate knowledge that distinguishes human beings from other living creatures. In my own case, to make myself of more worth to other people, I have never stopped pursuing knowledge through academic education, and more importantly, through real life experiences.

Life itself is the best school. When I explore ...

THESIS: “To benefit our economy and society, our national priority should be on encouraging more students to study STEM” (Adkins) that includes science, technology, engineering, and math.

Our economy and society need new generation of new technology innovators, however the number of STEM students has shrunk dramatically.

5% of U.S. workforce is employed in STEM related fields but they provide more than 50% of the country’s sustained economic expansion.

STEM-related disciplines can serve for the universal betterment of society.

Once the U.S. was the residence of high-qualified STEM experts, but today the number of them sharply decreased.

The urgent need to encourage students to study STEM requires taking some measures.

The size of the STEM education may be increased by maintaining an enthusiasm for studying science, technology, engineering and math among the high school or college students.

Public-private partnerships can also be of particular importance because students will be taught both theory and practice.

The composition of the ...

Stem cells are primitive cells capable of forming distinct types of tissue. Due to the remarkable quality, human stem cells are depicted to hold incredible for the development of various therapies to regenerate organs that are damaged as well healing suffering from terrible diseases. Embryonic stem cells are usually derived from human embryos. Their use is relatively controversial since such stem cells are in capacity to be harvested from bone marrow and umbilical cord blood, as well as other adult tissues without harm to the other. `Detailed research regarding adult stem cells is not yet intense and is still a ...

Complaining about Congress is almost a pastime in the United States, yet incumbents nearly always win re-election when they run. Congressional incumbents have several advantages and disadvantages when running for election, however, the advantages clearly outweigh the disadvantages as incumbents are very successful in running for re-election. Overall, it seems that the high rate of re-election for Congressional incumbents is a good thing. Over 90% of incumbents running for re-election are re-elected (347). Obviously there are many advantages to running as an incumbent. Several of these advantages stem from their name recognition and experience as a politician. Often, incumbents win re-election ...

Chapter One

Despite the fact that in 1996, Supreme Court Justice Scalia called single-sex education in public schools “functionally dead,” Single-sex education has become an increasingly popular model in schools since the No Child Left Behind Act of 2001 was passed. This federal legislation promoted innovative programs for states to implement that included single-sex classrooms and schools (U.S. Department of Education, 2006). Within any educational setting there were many factors that impacted student achievement that related to boys’ and girls’ physical, social, emotional, and intellectual needs. A single-sex environment provided boys and girls with a setting that promoted specific gender related ...

INTRODUCTION:

The stem cell research has been debated ever since the birth of it. However, the categorization of the stem cell research has been defined in a wrong manner. Moreover, the media is sensationalizing the topic. This has resulted in a wrong notion that all stem cell research is unethical. This is a wrong notion of the research because there are two types of stem cell research. The adult stem cell research is ethical than the embryonic stem cell research. Adult stem cell research refers to the usage of matured cells from mature adult human being without killing the host. On the ...

It encompasses a summary of the study and findings as well as the ethical considerations and overall effectiveness of the article. The framework for critiquing a quantitative article served as a guide in the writing of this research critique, which emphasizes the significance of interdisciplinary teaching and learning in the higher learning context, particularly as it pertains to climate change and the environment. Integrating social science with natural science is one such example highlighted ...

Women and the almighty dollar: why women make less than men and what can be done to change this income gap

Abstract

There are still men—and women-- who try to dismiss the existence of inequalities in the workforce, stating that there is no more need for feminism, and that society has achieved equality in the workplace. Nothing could be further from the truth—while advancements have been made, there is no doubt that there still needs to be a lot of work done to ensure that women are granted the same protections as men in the workforce. This is a discussion ...

Introduction:

Stem Cell Research has been one of the most controversial breakthroughs of science since the late 1990’s. The extraction of the human embryonic cell on that decade has made various responses in the medical field. This has opened many doors for many scientists that are highly interested in regenerative medicine. Additionally, this has also opened new debates about the ethics of the process of harvesting stem cells. There are two types of stem cell research. The first one is known as the embryonic stem cell research. The second one is named as the adult stem cell research (Shapiro, ...

The Human Immunodeficiency Virus (HIV) poses a serious threat to the well-being of people in different parts of the world. When the virus infects, body cells of a healthy individual, it weakens the immune system and makes an individual vulnerable to contracting to AIDS. In essence, this paper covers many aspects of the HIV virus including its pathophysiology, genomic factors, prevention, treatment, a comprehensive literature review among others.

Pathophysiology of the Disease Processes

Usually, the HIV causing virus binds itself onto cells often classified as CD4 alongside a co-receptor enclosed by a set of glycoproteins (Hammer & Squires, 2010). Notably, replication of DNA is dependent on an unreliable process, which ...

Human embryo stem cell research is an emerging field in medical science which has raised serious ethical issues. It is still a matter of debate whether or not this technique should be employed for the research purpose and what would be the end result of the embryo. Since the research process has advanced a lot, the prime focus at the present time is not to decide whether or not it should be done but to determine ways to maintain the privacy. The government looked into the matter of human stem cell research because those derived from animal sources had potential ...

Part one of this paper, “Sustainability and affordability in the design” lunges a functioning distinction between affordability and sustainability and proceeds to proffer a fabric of green building objectives. Additionally, it is discovered that the green building program excels in the following areas: durability, indoor environmental quality and efficiency. ...

Introduction:

Photoextraction uses plants to remove heavy metals and other contaminants from the soil. This can be a “two edged sword.” When animals consume them, can cause high concentration of contaminants on higher levels on up the food chain. Fortunately, they also present the potential for use as biomass in alternative fuel production. . Some species of plants are more effective as Photoextractants than others are. Other plant species are more effective when used as biomass. Ideally, plants used for Photoextraction should be capable of absorbing a spectrum of contaminants, and provide cost effective biomass. Testing is needed to determine if there are ...

Education is a conventional mode of receiving knowledge needed for people to pursue professional aspirations. What shape such aspirations are schools that narrow children’s scope of interests, determine the areas of expertise and, most importantly, provide with knowledge. To make school environment better in terms of efficiency, school officials came to introduce class differentiation years ago. The system of single-class schools had not regained its popularity with American parents until 2000s. On paper, single class schools handle the problem of bullying, however, not necessarily. Better school performance and mental skills development are believed to be the case in such ...

- The stromal cells that are found in the developing gonads of tetrapods begin from the medulla from the peritoneal wall and the cortex from inter-renal blastema or mesonephric. Hence the gonads have a dual origin. - Spermatogenesis occurs in a syncytial complex because it involves the formation of sperm from undifferentiated cells that are first attached to rachis. Syncytial cell complex or syncytium result when cells with single nuclei fuse to for a cell with nucleus. Syncytial cell complex is vital in oogenesis in that it assists in the differentiation of cells. One other developmental model is vitellogenesis. - ...

ABSTRACT

Muscular dystrophy disorders are hereditary neuromuscular disorders in which the skeletal muscles deteriorate progressively due to loss of the functional protein dystrophin encoded by the DMD gene. There are many types of muscular dystrophy and they are classified based on the genetic mechanisms involved. Muscular dystrophy symptoms are usually caused by mutations in the link between cytoskeletal and basal lamina proteins since dystrophin is a sarcolemmal membrane protein (Meregalli M, 2013). Loss of ambulation is also an important clinical milestone in the clinical diagnosis of muscular dystrophy. Respiratory muscles, particularly the intercostal and diaphragm muscles are also affected by muscular ...

Introduction

Placids can be defined as the endosymbiotic organelles, which substantially rely on the cell of their hosts to survive. Even so, placids are reported to have shown so much diversity in different situations. Therefore, ways through which differences emerge has been addressed. Some of the aspects that contribute to these differences are such as the difference in the lineages from which plastids originated. This is evident given that there are primary and secondary lineages from which the plastids can stem from. Additionally, the cause for the small size of the plastids has been established. Plastids are ...

President Bush and his administration must have felt the need to make changes in the educational system in America., a factor that propelled them to initiate the No Child Left Behind Act. However, they may have been right; their strategies on how to come up with a whole idea somehow proved flawed. What they did not perceive at that moment was that they needed to raise the standards of the schools. Nonetheless, going about it at the expense of a well-rounded education was not the right way of approach. It is an appreciation for President Obama together with Arne Duncan, Secretary of ...

Summary and Annotation of Literature: Thoreau’s Synthesizing Metaphor

“Thoreau’s Synthesizing Metaphor,” the author James A. Hamby explains the interpretation of metaphor that used in Henry David Thoreau literatures. Through out his works, Thoreau never halted to emphasize on the importance and the essence of life in connecting human beings to our nature, which is referred as “man-and-the-land relationships”. In one of his literature Walden, he united two antithetic terms “natural” and “pertinent” in demonstrating that his life is logical, reasonable yet natural and free, which the author thinks the way of adopting these two words showed Thoreau’s sweeping scope of concerns. In the chapter “Economy”, ...

Because they lack vessels that can bring the nutrients from the roots ...

Article Analysis

The article can be seen to focus on the effects of bone derived Mesenchymal Stem Cells that have been known to be highly controversial with their effects being adverse in some patients. In the article, they are focusing on testing on the hypothesis that Mesenchymal Stem Cells through mechanisms consisting of trilineage differentiation and long term engraftment regenerate the chronically infarcted myocardium. The article analysis these effects on different specimens hence coming with a conclusion in the end as to whether their hypothesis is correct or biased in some way.
